Welcome to Core Running! 

I'm the creator of this site and have been working with athletes from recreational level to professional for almost 25 years. While I work primarily with runners I've also helped cyclists and triathletes to personal best performances.

I understand the challenges of trying to push your limits while also having the responsibilities of work and family. Sometimes it can be a tricky balancing act but I can help you reach your athletic goals while still being an involved parent and high achieving career professional. Click Here for My Bio

Curb is an excellent coach who cares about his clients.

Thanks to Curb’s coaching, I have been able to take off almost 30 minutes from my marathon time and have seen significant race improvements in my half marathon and shorter distance races.

You...were a considerable help in my being able to achieve much more than what I thought possible. In the 2017 Whistler Gran Fondo I was 7:24:58, in last year’s 7:18:04. This year my goal was to get under 7:00, with a target finish of 6:58.
So I officially was 6:31:09 which far exceeded my expectations.

As a long time athlete that was new to running, I needed help and Curb was great.  

He provided me with a training plan customized to me and also provided me with additional guidance on everything I needed along the way.
